adding more moles of a particular substance
shifts opposite of side of that substance to equalise it
removing a moles of substance of a particular substance
shifts the equiliblibrium to the side where we took away moles to equalise it
which way will equilibrium shift if heat is added to the system ex: 2 SO2+O2=2 SO3 + heat
the system will try to useup the heat and therefore shift left
which way will equilibrium shift if heat is removed from system (given off from reaction)
the reaction will shift to the right to the right to replace the used up heat because equilibirums shift to side opposite of stress
volume reduction
the equilibrium shifts to the side with less moles to lessen the pressure
volume addition
the equilibrium shifts to the side with more mores to equilise the pressure to equilibium
adding catalyst
no changes just speeds up time to get to equilibirum
what is exception to pressure changes
if equal amount of moles on each side
Le Chatelier’s Principle
placing stress on equilibirum causes it to shift to relieve the stress
